This lint.ermediate stem diate its ends with baille means comprising theannular flanges I9 and 20 which serve to trap moisture and to direct thecourse of travel 'of the smoke through the stem in a manner to behereinafter described.

The annular flanges and the collar portions cooperate to formperipherally disposed annular channels forming smoke compartments.

At the inner end of the mouthpiece I5 there is provided a threadedbushing 2| cooperating with a correspondingly interiorly threadedportion of the passage |51) of said mouthpiece. The bushing 2| has apassage 2 Ia therethrough which is of less diameter than the passage I5bof the mouthpiece. In practice, a plurality of bushings 2|, havin-gpassages 2|a of different diameters, may be provided for alternative useto suit the whim of a smoker who may desire to have a pipe which drawsmore or less freely, depending upon the size of the passage 2|a of thebushing emv ployed.

ber 22 surrounding a portion of the stem member l 'I I. The socketportion I4 of said stern member is'provided with radial openings 23 at apoint adjacent the inner end of the mouthpiece I5, through whichopenings 23 smoke from the superchamber may pass to the passage I5b ofsaid mouthpiece through a bushing 2|, if such be employed.

The inner end of the mouthpiece I5 will extend into the socket portionI4 a distance suilicient to provide adequate space between the inner endof said mouthpiece and the openings 23 in said socket, whereby to permitof adjustment of the bushing 2| toward and away from said openings 23 byturning the head 2| b of said bushing. Thus` the said bushing may beemployed to act as a damper for regulating the draft through themouthpiece I5 by adjustment of the head 2Ib of said bushing toward andaway from the openings 23, since the diameter of thehead 2 Ib issubstantially the same as, or slightly less than, the inner diameter ofthe socket portion I4. Hence, if the bushing 2| is unscrewed a few turnsso as to move the head 2| b to a position opposite the openings 23, thedraft through said openings will be dampened, and, likewise, when thebushing 2| is screwed into the mouthpiece so that the head 2Ib abuts theinner edge thereof, the draft through said openings will becorrespondingly increased.

In operation, the sleeve I8 will be positioned as shown in Figure l andthe chamber 2 of the bowl I will be loaded' with a quantity of tobaccopacked therein against the ange portion 1 which serves to support thetobacco so packed in said bowl.

` As above stated, the space between the circumferential edge of theange 1 and the adjacent inner wall of the chamber 2 is suflicient topermit smoke from the lighted tobacco to be drawn downwardly and throughthe passage 9, while at the same time preventing any substantial amountof tobacco from falling below the supporting surface of the flange 1.

As a smoker draws upon the mouthpiece I5, the smoke from the lightedtobacco will pass from the passage 9 through the passage I2 out throughthe openings I3 into the superchamber 22, and by reason of theinter-position of the anges I9 and 29 substantially all of the smokewill be caused to impinge the inner surface of thesleeve I8 as saidsmoke passes toward and through the openings 23 of the socket portionI4, and thence through the passage 2Ia of the bushing 2|, and throughthe passage I5b of the mouthpiece I5 into the mouth of the smoker.

In the process of smoking the pipe embodying the improvements of myinvention, moisture condensed out of the tobacco will be trapped uponthe upper surface of the flange 1. By reason of the fact that saidilange is made of metal and becomes hot during the process of smoking,moisture so trapped will be dissipated by the heated metal, andconsequently Will not get into the passage 9, or if carried into saidpassage in the form of vapor will subsequently condense in, and adhereto, the walls of the passages 9 and I2 and the inner wall of the ysleeveI8, or said moisture will condense upon the trapping flanges I9 and 28,or the intermediate portion Ila ofthe stem II so that very little, ifany, moisture will pass into the mouthpiece I5 to interfere with theenjoyment of the smoker using said pipe. i

If, during `the process of smoking, and without interrupting saidprocess, or disassembling the pipe, it is desired to clean the stemmember II, or remove accumulated moisture therefrom, it is onlynecessary to slide the sleeve I8 to the position shown in Figure 2 toafford ready access to said stem member for this purpose.

It will readily be apparent that when the sleeve member I8 ispositioned, as shown in Figure 2, it is a very simple matter to cleanthe exterior of the stem member II employing a cloth for that purposeand to run a pipe cleaner into the passages I2 and 9 through theopenings I3, or even to run the pipe cleaner through the openings 23without necessitating removal of the pipe from the mouth of the smoker,if desired.

When it is desired to clean the bowl I of the pipe the false bottom 3may be readily unscrewed to remove the same forfacilitation of suchoperation as will be apparent.

As seen in Figure 3, I have provided a pipe testing device which may bereadily attached to the mouthpiece of the pipe of a type herein referredto. Said testing device comprises a length of rubber tubing, generallyindicated at 24, the portion 24a. 0f which may be of somewhat more rigidconstruction than the inner portionv 24h which is preferably moreresilient to enable the same to be fitted over the mouthpiece I5 of apipe as shown. A thermometer 25, which has had Aits tubular portioninserted through la suitable opening in the portion 24a of the tube 24,has its bulb portion25a positioned interiorly of said tube portion 24aand is more o-r less firmly supported thereby. An auxiliary mouthpiece28, which may be of a construction similar to the regular mouthpiece I5of the pipe, is provided for insertion in the outer end of the tubeportion 24a. In use, a smoker may readily test the coolness of the smokewhich passes through the mouthpiece |5of his pipe by noting the heightof the column of mercury in the thermometer 25 as the smoker draws thesmoke from said mouthpiece I5 through the rubber tubing 24 and auxiliarymouthpiece 26.

portion, said bowl being provided witha tobacco It will be noted thatthe bottom surface 4a ofk the base portion lof the removable falsebottom 3 is preferably made flat so that the pipe is supported with thebowl I in an upright position as shown in Figure 1 when placed upon aflat surface, such as a table top or the like.

When a pipe constructed as herein disclosed is being smoked,substantially all of the smoke drawn through the stem is caused toimpinge theA inner surface ofthe metal sleeve I8. 'I'his result iseffected by reason of the interposition of the flanges I9 and 20 whichare of a diameter only slightly less than that of the said inner wall ofthe sleeve. The smoke is compelled to impinge the inner surface of thesleeve in order to p'ass throughvthe small space provided between saidsleeve and the. edgesof said flanges. Because of the extended area ofthis impingement of the smoke with the sleeve, a marked cooling of thesmoke drawn through the stem results, since the sleeve'is made of heatconducting material which enables the heat of the smoke to be conductedout of the stemand hence dissipated.

Besides their function just mentioned, the flanges I9 and 20, and, infact, the entire intermediate portion of the stem, function as filtermeans to entrap moisture and juices from the tobacco and also to entrapsaliva passing from the smokers mouth.

The sleeve I 8 is preferably provided with longitudinal slits I8a at itsends to permit a slight crimping of the ends of the sleeve to enable thesame to t more tightly over the' collar portions I6 and I1 when thesleeve'is in the closed {position of Figure 1. Preferably, also, thediameter of the sleeve I8 is gradually diminished from its leftwardtoward its rightward end having reference to Figures 1 and 2 so that thesaid leftward end of the sleeve will pass over the collar portion I'Iloosely when moved toward and from the position of Figure 2 and bothends of the sleeve will fit snugly on their respective collar portionsI6 and I1 when the sleeve is in the position of Figure l.

Having thus described m'y invention, what I claim as new and desire tosecure by Letters Patent of the United States is:
